I have a 2006 Holiday Rambler, the other day I pulled the battery tray out to check the level of the fluids, whoever owned this unit before us put what appears to be baking soda in the trays to prevent corrosion I guess, I have heard of this working.
Anyway has anyone tried to use the spray0n rubber liner like for P/U Beds??
It claims to be acid resistant and would sure look better than a tray full of white powder.
